Curated OER
Draw your Conclusions
Pupils analyze data from a student discussion website and write a report on the outcome of an investigation regarding their local water quality. As part of a larger unit students then post the summary of their investigation on the...
Curated OER
Build a Bug
Students design an ideally adapted macroinvertebrate to live in a water habitat. They illustrate their animal, name it and specify the adaptations it has that enable it to survive.
Curated OER
Into the Pond
Seventh graders use a pond to explore macroinvertebrates and other organisms. They use a dichotomous key to classify the organisms and maintain a journal recording their findings.

Determination of Overall Water Quality Using a Quantitative Macroinvertebrate Survey
Students examine water samples from a local stream. They identify various types of macroinvertebrates found in that water ecosystem and perform a quantitative macroinvertebrate survey to determine the stream's water quality.

Do Human Practices Affect Water Quality?
Students determine if human practices have any noticeable effects on the quality of stream life as measured by the presence of certain macroinvertebrates. They collect, preserve and identify macroinvertibrate samples and quantify the data.
